Sturdy potholder lom with cotton loops. Both the frame and loops are high quality. Loops are 100% cotton made in textile mill in NH. Bought for grandkids but I'm also enjoying it. The 5 yr olds like string the loops in first step then picking out colors for the cross weaving. The 7 yr old can do both weaving steps (almost) but needs little help taking off the frame. Instructions are clear with suggestions for patterns.. Great product...
